A Direct-Reading Device for Use in Computing Characteristics of Vacuum Tungsten Lamps (Classic Reprint): With Computing Chart: With Computing Chart (Classic Reprint) - Softcover

Inhaltsangabe

A practical, single-setting chart system for analyzing tungsten lamp performance.

This book explains how to compute candlepower, watts per candle, and voltage with one setup. It focuses on a chart-based device that links observed values to a normal reference and delivers quick results.

Designed for technicians and students, the material covers the scales, how to use them, and how to read results directly from the cp and wpc scales. It shows how to set voltage, observe candlepower, and read the corresponding values from the chart, with guidance on interpolation and accuracy. The text also discusses the construction of cp curves and the logic behind using logarithmic scales to simplify calculations.

What you’ll experience:

• How to align observed values with the initial cp line and read cp and wpc at different voltages.
• Steps for using the volts, wpc, and normal cp scales together to obtain results fast.
• Explanations of the per cent cp curves, their straight-line behavior, and how they relate to voltage and wpc.

Ideal for readers who work with lamp measurements, calibration, or education in electrical characterization of tungsten lamps.
